Gee in one picture I think I can see a Radio Moscow sticker (In Cyrilic script of course).and a serial "Woodpecker #3". But my eyes aren't what they used to be. With this dudeyou could save on gas or fuel oil in the winter with the filaments on.

Unless there's more to that amp than is shown, I'd think the filament pins would all unsolder themselves with any kind of use, as I don't see any air flow cooling them under the sockets...

So what's the problem, he has THREE impressive fans blowin' on the tubes. What more do you want?
